Abstract：Aimingattheproblemof traficcongestioncausedbytheuncertaintyandunpredictabilityof raficflow，whichaffectedtheeficiencyofcoldchaindistribution，thispaperproposedthecoldchainvehicleroutingproblemwithtimewindow considering traficcongestion（CCVRPTWCTC）andconducted theO-1integer programming model.Then，itproposed theimprovedimmune genetic algorithm byvariable crosover operation andadaptive perturbation operators，andnamed immune geneticalgorithmbasedonvariable cross descent （VCD-IGA）.Finall，itconducted experiments using actual distributiondata andtraficflowdatainthedistributionprocessofafreshfoodenterprise.Itconductedtheexperimentsthroughanautonomous informationsystemfordatainteractionandreal-timedynamicoptimizationof distributionpathsthroughtheproposed VCDIGA.The experiments show that the proposed dynamic decision leads to a 29.6% reduction in the total distribution cost and an 18% increase in the average logistics service level compared to the static decision.
